Description: 1. DS3231 is a Real Time Clock (RTC) Memory Module that comes with a built-in battery (CR2032) pack of 25, enabling it to maintain accurate timekeeping even during power outages. 2. This RTC module features an I²C interface and can be easily interfaced with microcontrollers like Arduino, Raspberry Pi, PIC, etc., for real-time clock and calendar functions. 3. The DS3231 operates on a +3.3V to +5V power supply range and offers an accuracy of ±10 parts per million (ppm), making it suitable for applications that demand precise timekeeping. 4. This RTC module includes an onboard temperature sensor, enabling users to monitor the temperature alongside maintaining accurate time information. 5. The DS3231 supports various calendar functions such as setting the date (day, month, and year), time (hour, minute, second, and AM/PM), and day of the week. 6. This RTC module offers a unique alarm feature that can be set for specific dates and times, making it perfect for applications requiring sc
